What is a downstream injector

A downstream injector is a device used to inject chemicals or detergent into the flow of water after the pump on your pressure washer. This differs from an upstream injector which injects chemical before the pump.

How does a downstream injector work?

A down stream injector works by Venturi effect. Simply put this means that the water from the pressure washer is pushed into a constricted section in the injector. As a result the increased velocity of fluid creates a vacuum, drawing in the solution.

What is an upstream injector?

Upstream Chemical Injector – SUT64 Designed to introduce detergents (high pressure soap applications) into the water system upstream from the pump at a high pressure.

What is downstream injection?

Downstream injection is a means of applying chemicals with the use of a pressure washer. … Downstream injection introduces chemical into the system after the pump, so no chemical is ran through the pressure washer pump itself.

How do you test downstream injectors?

Test your upstream or downstream injector by getting a metering jug that measures ounces and fill it with water and put your soap line into the metering jug and draw the water for 1 minute. This will allow you to see how many ounces your soap injector is drawing in a minute.

How much does a downstream injector dilute?

All downstream injectors will dilute your mixture. In order to use a downstream injector, the end solution of the chemical being applied must be effective at dilution rates of 8-1 and higher.

Can you use bleach in a downstream injector?

Solution: Use a typical 20 / 1 venturi style chemical injector. Do not exceeded 150 feet of pressure hose. … Your 20/1 downstream injector will now pull the bleach and Green Wash solution through and your final cleaning solution at the wands tip will be . 06% bleach to water or about one half of a percent overall bleach.

What is a XJET?

The X-Jet is a nozzle that connects to a pressure washing gun and lets you shoot a variety of chemical mixes, including bleach, up to 40 feet safely from the ground. It’s a great option for soft washing because you can use it with your existing power washing equipment.

How does chemical injector work on pressure washer?

So a chemical injector has a restrictive orifice that the water stream is forced through. It also has a small port that chemical is drawn into because of the vacuum created. … Operating with low pressure at the nozzle reduces pressure on the outlet port, and the suction draws the chemical into the water stream.

What is chemical injection?

As the name implies, a chemical injection system is a piece of equipment designed to inject chemicals into a system at the required pressure for the system. It may function continuously or intermittently, and it can be used in a wide range of settings for many different purposes.

What does a down Streamer do?

If you have low pressure going through, around 100 PSI or less, it allows the valve to remain open and will draw soap from the soap tank into your line. If you have high pressure the valve will shut off and no soap will be drawn.

What is SH in pressure washing?

SH, Sodium Hypochlorite, Liquid Chlorine, Laundry Bleach, etc. This chemical is used in many ways in the pressure washing industry to make some serious cash. … The bleach used in this industry should be stronger than household bleach.

What is Elemonator?

Elemonator is a liquid house wash and multipurpose cleaner that not only is bleach stable but also boosts the pH of bleach. It has great foaming and rinsing properties and the strong lemon scent does a great job of masking the smell of bleach.

How do you get soap out of a pressure washer?

Make sure you are using the proper soap siphon setting or nozzle. Refer to operator’s manual for correct application. Slowly close the water supply valve while spraying the soap nozzle until suds are visible. Test for blockage: Remove the high-pressure hose from the pump and start the engine.

Can you run bleach through a dishwasher?

Pour 1 cup of bleach into a dishwasher-safe, bleach-safe bowl and place it on the top rack of your dishwasher. Then run a full cycle, but skip the drying cycle. … Also, do not use bleach at the same time you clean with baking soda or vinegar.

What chemicals do pressure washing companies use?

Definition of downstream 1 : in the direction of or nearer to the mouth of a stream floating downstream located two miles downstream. 2 : in or toward the latter stages of a usually industrial process or the stages (such as marketing) after manufacture improving profits downstream downstream products.

What is downstream pressure?

The downstream pressure after an obstacle will always be lower than the upstream pressure, producing a pressure drop across the obstacle cum flow element. All these types of flow elements are differential producers and require a DPT to measure the pressure drop and convert it to a compatible linear signal.

What size is XJET hose?

The stock X-Jet M5 Vinyl Tubing is 3/8ID 5/8OD.

What is a downstream detergent?

Downstream delivery has the cleaning agents brought into the washer without clearing the pump. If there are chemicals you need to use that may be too hard on your pump, such as bleach as one example, this would be the way to go.
